Can we set containerized_deployment per service?

I notice that the "switch from non-containerized to containerize" ceph-ansible https://github.com/ceph/ceph-ansible/blob/master/infrastructure-playbooks/switch-from-non-containerized-to-containerized-ceph-daemons.yml (playbook) sets the containerized_deployment parameter per service. Does this mean that we could deploy, for example, osd, manager and admin as containers, and then RGW as a bare metal service? Would that work?
